Universal amorphous-amorphous transition in GexSe1-x glasses under pressure
Can Yildirim, Matthieu Micoulaut, Punit Boolchand +5
Pressure induced structural modifications in vitreous GeSe (where 10 x 25)are investigated using X-ray absorption spectroscopy (XAS) along with supple…
Designing heavy metal oxide glasses with threshold properties from network rigidity
Shibalik Chakraborty, P. Boolchand, M. Malki +1
Here we show that a new class of glasses composed of heavy metal oxides involving transition metals (VO5-TeO), can surprisingly be designed from ve…
Superstrong nature of covalently bonded glass-forming liquids at select compositions
K. Gunasekera, S. Bhosle, P. Boolchand +1
Variation of fragility (m) of specially homogenized GexSe100-x melts are established from complex specific heat measurements, and show m(x) has a global minimum at an extremely low…
Melt homogenization and self-organization of chalcogenides glasses: evidence of sharp rigidity, stress and nanoscale phase separation transitions in the GexSe100-x binary
S. Bhosle, K. Gunasekera, P. Boolchand +1
A Raman profiling method is used to monitor growth of GexSe100-x melts and reveals a two step process of homogenization. Resulting homogeneous glasses show the non-reversing enthal…
Rare-earth monosulfides as durable and efficient cold cathodes
M. Cahay, S. B. Fairchild, L. Grazulis +10
In their rocksalt structure, rare-earth monosulfides offer a more stable alternative to alkali metals to attain low or negative electron affinity when deposited on various III-V an…
Fast-ion conduction and flexibility and rigidity of solid electrolyte glasses
M. Micoulaut, M. Malki, D. I. Novita +1
Electrical conductivity of dry, slow cooled (AgPO)(AgI) glasses is examined as a function of temperature, frequency and glass composition. From these data compositi…
